PDF of 336 KB covering the 2SC732TM, an NPN bipolar transistor of the Japanese 2SC family; the TM suffix appears in the name but is not explained. Classified as a schematic in the index, it most likely holds a component datasheet. Open it to check pin order, maximum ratings, noise and gain data and the outline drawing. Such small-signal parts are common in older audio stages, so compare the gain class letter on the original component when picking a replacement.
